Add or Remove Network from Navigation Pane in Windows 10  

Already done that. Trust needs to be deleted. SO no changes can be made to that until trusted installer is removed.

I see no Administator in the bottom!
Only Users and AdministratorS.. so You have two groups with full access and the owner with no access!
You need to add it and grant that user full access! Even if he is in the group with others!
I changed ownership from trustedinstaller to AdministratorS.. I am not sure if users on my comp have full access I prefer Users to have in file system becouse Users are Interactive User (have access to console) and .. damn I forgot.. Authenticated User.. I guess. (user who had account on local comp)

Well.. I gave it read acces and have it in case I need it.. but I can hardly stand it.. As far as I know it's still 32bit local servis.. we are deep in 64bit era..

i have no idea what you are writing about since the picture I posted shows admin in the bottom and owner is there also. So show pictures if you have something different then I have because U have confused the Portagie.
